ignore_user_abort

(PHP 4, PHP 5, PHP 7)

ignore_user_abort — Set whether a client disconnect should abort script execution

Description

int ignore_user_abort ([ bool $value ] )

Sets whether a client disconnect should cause a script to be aborted.

When running PHP as a command line script, and the script's tty goes away without the script being terminated then the script will die the next time it tries to write anything, unless value is set to TRUE

Parameters

value

If set, this function will set the ignore_user_abort ini setting to the given value. If not, this function will only return the previous setting without changing it.

Return Values

Returns the previous setting, as an integer.

Examples

Example #1 A ignore_user_abort() example

<?php
//?Ignore?user?aborts?and?allow?the?script
//?to?run?forever
ignore_user_abort(true);
set_time_limit(0);

echo?'Testing?connection?handling?in?PHP';

//?Run?a?pointless?loop?that?sometime?
//?hopefully?will?make?us?click?away?from?
//?page?or?click?the?"Stop"?button.
while(1)
{
????//?Did?the?connection?fail?
????if(connection_status()?!=?CONNECTION_NORMAL)
????{
????????break;
????}

????//?Sleep?for?10?seconds
????sleep(10);
}

//?If?this?is?reached,?then?the?'break'?
//?was?triggered?from?inside?the?while?loop

//?So?here?we?can?log,?or?perform?any?other?tasks
//?we?need?without?actually?being?dependent?on?the?
//?browser.
?>

Notes

PHP will not detect that the user has aborted the connection until an attempt is made to send information to the client. Simply using an echo statement does not guarantee that information is sent, see flush().
